Automated Pupillometry in Patients Underwent Cardiac Surgery to Predict Postoperative Delirium

"Pupillary variables in both eyes are recorded and measured with NPi-200 every 30 minutes from the induction of anesthesia. At the end of the surgery, the patient is transferred to the intensive care unit (ICU), and the pupillary variables are recorded until the patient regains consciousness (Richmond agitation sedation scale, RASS\>-3). Specific hemodynamic, respiratory, surgical, and EBP data are also recorded as well as NIRS variables.~As soon as the patient had regained consciousness (RASS \> 3), they were assessed for delirium for a total period of five days. Nursing and/or medical staff administered the CAM-ICU score to patients twice a day (morning and afternoon)."
